Code B1405 2017 Chevrolet Silverado Description

The parking assist sensors are 3-wire ultrasonic sensors that are used to determine the distance between the vehicle and an object. The Parking Assist Control Module supplies a reference voltage to the parking assist sensors via the Parking Assist Sensor Reference Voltage circuit and provides ground via the low reference circuit. The Parking Assist Control Module triggers the sensors in a sequential loop. After each sensor transmits, the 6 Parking Assist Control Module uses the sensor echo received through the signal circuit to calculate the distance and position of an object.
